Sulfo NHS-SS-Biotin Product Description

Sulfo NHS-SS-Biotin is a reducible, long-chain amino reactive biotinylation agent. Sulfo NHS-SS-Biotin reacts with molecules containing primary amine (-NH2) residues, including small molecules, proteins, antibodies and other biomolecular compounds.

Sulfo NHS-SS-Biotin contains a biotin moeity, an elongated spacer arm with a reducible disulfide (S-S) and an active, amine reactive NHS ester. This biotinylation reagent can be added directly to aqueous reactions, or can be dissolved in a high quality, molecular biology grade, anhydrous solvent, such as DMSO (CovaChem 18252) or DMF (CovaChem 18251) prior to adding to final aqueous reaction buffer.

Sulfo NHS-SS-Biotin labeled proteins can be cleaved through the fascile reaction with TCEP (CovaChem 11303) or DTT (CovaChem 11302), allowing for quantitative release of biotin tag.

  • EDC-HCL | EDAC-HCL | > 99%

    N-Ethyl-N'(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC-HCl) is a zero length protein crosslinker. Also known as EDAC-HCl, this reagent is often used with either Sulfo-NHS (CovaChem 13505) or NHS (CovaChem 13504). EDC functions by activating the carboxyl region of the protein or other molecule, and coupling it to an amine or other nucleophilic functional group.

  • EMCS Crosslinker

    N-(∑-Maleimidocaproyloxy) succinimide ester(EMCS) is a heterobifunctional crosslinker with a spacer length of 9.4 Å. EMCS contains an amine reactive, NHS ester, and a maleimide group which is reactive towards sulfhydryl functional groups.

  • LC-SPDP Crosslinker

    Succinimidyl 6-[3-(2-pyridyldithio)propionamido] hexanoate (LC-SPDP) is a heterobifunctional crosslinker that is amino reactive on one end and sulfhydryl reactive on the other end. LC-SPDP contains a long spacer arm (15.7 Å)for increased molecular flexibility and a reducible disulfide, which is allows for cleavage of the crosslinker after crosslink formation.

  • LCMS Grade Propionic acid (UltraPure)

    LCMS Grade Propionic acid (Ultra High Purity) from CovaChem is well suited for HPLC and LCMS applications. Propionic acid can be used as a mobile phase for HPLC or LCMS, or can be used post-column in LCMS applications to increase ionization efficiencies when ion pairing agents are used for separation.
